Does Sct Livewire Monitor Egt? My Frustrating Search
Seriously, you spend hours digging through forums, watching YouTube videos that all sound like they were sponsored by the same company, and you still can’t get a straight answer. That’s what it felt like trying to figure out if the SCT Livewire could actually track Exhaust Gas Temperatures. It’s maddening when you’re trying to get serious about tuning your vehicle and the tools themselves are shrouded in ambiguity.
I remember the first time I bought a tuner, thinking it would solve all my problems. Waste of money. Then I shelled out for another, convinced *this* was the one. Nope. The marketing hype around vehicle monitoring is relentless, promising the moon and delivering a glow-in-the-dark sticker.
So, does SCT Livewire monitor EGT? Let’s cut through the noise.
The Cold, Hard Truth About Sct Livewire and Egt Monitoring
Look, I’ve been down this road more times than I care to admit. Spent hours staring at glossy product pages, squinting at tiny spec sheets, and feeling my wallet get lighter for absolutely no gain. When it comes to the SCT Livewire and EGTs, the answer isn’t a simple yes or no. It’s… complicated. And frankly, I’m tired of the vague marketing speak that dances around the issue.
For years, the general consensus I found, after what felt like reading a thousand forum posts and about three actual technical manuals, was that the Livewire *couldn’t* natively monitor EGTs out of the box. You needed aftermarket add-ons. This is where I’d usually throw my hands up and look elsewhere. But then I stumbled across a few guys who insisted it *was* possible with the right setup, which sent me down another rabbit hole. It’s like trying to find a decent cup of coffee in a desert of instant packets.
My personal nightmare fuel was a setup I bought for a previous truck. It was supposed to do everything – monitor boost, EGT, air/fuel ratio, the works. I spent around $450 on the unit and the sensors, only to find out the actual logging capability for EGTs was… rudimentary at best. It would jump around like a scalded cat, completely unusable for any serious tuning. The screen flickered, the menus were clunky, and the user interface felt like it was designed by a committee of engineers who’d never actually seen a truck. Seven out of ten times, I’d get a ‘sensor error’ message, which was about as helpful as a screen door on a submarine. That money is still sitting in my imaginary ‘lessons learned’ fund.
When ‘monitoring’ Isn’t Really Monitoring
Here’s the core of the issue, and it’s where most people get tripped up. Does SCT Livewire monitor EGT? Technically, no, not directly through its built-in inputs without additional hardware. Think of it like this: You have a smartphone. It can make calls, send texts, browse the web. Can it measure the exact temperature of your coffee? Not without a special attachment, right? The Livewire is similar. It’s designed to read parameters that your vehicle’s ECU (Engine Control Unit) already broadcasts. EGTs aren’t typically standard OBD-II PIDs (On-Board Diagnostics II Parameter IDs) that your truck readily spits out. (See Also: Does Having Dual Monitor Affect Framerate )
So, if you plug in a Livewire to a stock truck, you’re not going to see an EGT gauge magically appear. It’s like expecting a calculator to also brew you a perfect espresso. It just doesn’t have the inherent functionality built-in. This is where the confusion starts, because many aftermarket tuners *do* offer EGT monitoring, but they often achieve it through dedicated inputs designed for pyrometers or other sensors.
Why You Need More Than Just the Tuner
This is the part that irritates me. The marketing often implies that one device does it all. It’s a common tactic in the gadget world, trying to sell you a single box that’s supposed to be the ultimate solution. But with EGTs, you’re almost always looking at a two-part system: the tuner itself, and the EGT sensor setup. The SCT Livewire, in its standard configuration, isn’t equipped with the necessary analog inputs to read a pyrometer, which is the common sensor used for EGTs.
You’ll need a pyrometer sensor and often a separate module or a way to integrate that sensor’s signal into a system the Livewire *can* read. Some people use dedicated EGT gauges that then feed their data into a device like the Livewire if it has logging capabilities for external inputs. Others might use a data acquisition system that the Livewire can interface with. It’s not impossible, but it requires extra steps and, let’s be honest, extra cash. I’ve seen people spend upwards of $300 just on a decent EGT sensor kit and wiring harness to get this information, only to find out their tuner still struggles to interpret it cleanly.
The sensor itself can be a finicky thing. You have to install it correctly, usually in the exhaust manifold or near the turbo, and the wiring needs to be routed carefully to avoid heat damage or interference. It’s not a ‘plug and play’ situation like checking tire pressure. It requires mechanical aptitude and a certain level of patience that, frankly, I don’t always have after a long day.
What About the ‘custom’ Tunes?
Ah, custom tunes. This is where things get even murkier. Some custom tuners might be able to configure the SCT Livewire to read EGTs if they’re utilizing a specific method of data logging or if they’re using a companion device that can translate EGT sensor data into a format the Livewire can display. This isn’t common, and it’s definitely not a standard feature. It’s more like a hack or a specialized integration.
Think of it like this: If you have a really talented chef, they might be able to make a gourmet meal with ingredients you wouldn’t expect. But you can’t just walk into any restaurant and expect them to do it. Similarly, not every tuner will know how to, or even be able to, get the Livewire to display EGTs. You’d need a tuner who is experienced with the Livewire’s advanced capabilities and knows how to bridge the gap between an EGT sensor and the tuner’s data streams.

I’ve talked to several tuners who flat-out said, “No, the Livewire doesn’t do EGTs.” Then I’ve spoken to others who said, “Yeah, but you need this specific sensor, and I have to write a custom PID for it.” It’s enough to make your head spin. For most users simply buying an off-the-shelf Livewire and expecting EGTs is going to lead to disappointment. The data you *can* see natively – like boost, engine load, injector pulse width, and RPMs – is crucial, don’t get me wrong. But for serious performance monitoring, especially if you’re pushing your engine hard, EGTs are a big piece of the puzzle.
The common advice you’ll see is to get a separate, dedicated EGT gauge. And honestly, that’s often the most straightforward and reliable path. It’s like choosing a dedicated hammer for hammering nails, rather than trying to use a wrench for everything. While the Livewire is a powerful tuning tool for what it *is* designed for, relying on it for EGTs without significant modification is asking it to do a job it wasn’t built for.
According to a general consensus in many automotive performance forums and specialist tuning shops, and echoed by advice from reputable performance parts manufacturers like Banks Power and Edge Products who often discuss sensor integration, relying on the Livewire alone for EGT monitoring is not a standard function. These sources highlight the need for dedicated pyrometers and often separate monitoring systems or tuners with specific inputs for EGT sensors.
The Competition: What Else Is Out There?
It’s worth glancing at what competitors offer, not to copy them, but to understand the market. Some tuners and monitors *do* have dedicated EGT inputs. For example, devices like the AEM X-Series gauges are specifically designed for this, and they can often be integrated into a larger data logging system. Other tuners, particularly those focused on diesel applications, might have built-in EGT monitoring capabilities because it’s considered more of a standard requirement in that segment.
This isn’t to say the SCT Livewire is a bad tuner; it’s great for what it does. But if EGT monitoring is high on your list, you need to be aware of its limitations. It’s like buying a high-end camera and then wondering why it doesn’t have a built-in projector. It’s not its primary function.
Here’s a quick look at how it stacks up, from my perspective: (See Also: How Does Bigip Health Monitor Work )
| Feature | SCT Livewire (Standard) | Dedicated EGT Gauge/Monitor | Opinion |
|---|---|---|---|
| EGT Monitoring | No (requires add-ons/customization) | Yes (primary function) | For EGTs, dedicated is king. |
| Tuning Capabilities | Excellent | N/A | Livewire shines here. |
| Ease of Installation for EGTs | Complex (if possible) | Moderate (sensor install) | Separate is simpler for EGTs. |
| Data Logging (General) | Good | Varies | Livewire is good for general vehicle data. |
So, Can I Make My Livewire Show Egts?
Yes, but it’s not straightforward. You’re looking at adding a pyrometer sensor, and then figuring out how to get that signal into the Livewire. This might involve a separate data logger that can then be read by the Livewire, or if you have a tuner who is a wizard with custom PIDs and knows the Livewire inside and out, they *might* be able to configure it. But for the average user, it’s an uphill battle. I’ve seen people get frustrated trying this for months, spending money on parts that ultimately didn’t work with their specific Livewire firmware or vehicle combination. It’s a bit like trying to teach a cat to fetch the newspaper; it’s theoretically possible with enough training and treats, but highly unlikely to be a daily occurrence.
Ultimately, if EGT monitoring is a must-have for your tuning strategy, you’re probably better off looking at a dedicated EGT gauge or a monitoring system that natively supports pyrometers. Trying to force the Livewire to do this is often more trouble than it’s worth, and the results can be unreliable. The Livewire is a fantastic tuning device for engine parameters it’s designed to read, but when it comes to EGTs, it’s usually a no-go without significant extra effort.
Verdict
After all the digging, the frustration, and a few more gray hairs, the honest answer for does SCT Livewire monitor EGT is a resounding ‘not easily’. Without adding specific hardware and potentially complex custom configurations, you won’t find that crucial exhaust gas temperature data on its stock display. It’s a tool built for reading what the ECU already gives it, and EGTs typically aren’t on that standard menu.
If your goal is to monitor EGTs for serious tuning or engine protection, and you’re not looking to become an electronics expert, your best bet is to look at a dedicated pyrometer and gauge setup. Trying to jury-rig an EGT reading into the Livewire can be a costly and time-consuming endeavor with unreliable results. I spent around $200 on various adapters and interfaces that ended up being useless for my setup before I finally admitted defeat and bought a standalone gauge.
It’s a shame, because the Livewire is a capable device for what it’s intended for. But when it comes to the specific question of does SCT Livewire monitor EGT, the reality is you’ll likely need to supplement it significantly, or just go with a different solution altogether for that particular data point.
